Patented June 14, 1932 l-JNITEDI STAT- Es PATENT OFFICE GEORGE W'. ZBTCHELI/J, OF TOLEDO, OHIO FEEDING MOETEN GLASS Applieatlon med November '1,l 192s. serial No. 317,808. l

5 control in providing from a iixed trough a uniformly H uid exposed region adapted for top or suction gather, while additionally there may be further molten glass removed, sayfor downward flow off as gob gathering. Il) 4 eferring to the drawing: Fig. 1 1s a lan view,L with parts broken away, of an em odiment of the invention;

Flg. 2 1s a partial section on the line IIe-II,

v3 is a partial section on thel line f/Glass furnace or tank 1 may have therein popl 2 as a supply of molten glass. From th1s pool there may be openin 3 in communi- '10 cation with way 4 as a troug herein shown as having direction change region 5 with open top 6, there to expose upper surface 7 of the molten glass from the supply 2, so thatI gather cup 8 with suction line 9 thereon may 25 upwardly lift or remove a gather of glass in the travel of the machine say in continuous operation past said region of e osed molten glass.' The wa 4 as continuing ast the region 5 exten to terminal 10 s own as n 39 having draw-olf or bottom* discharge open- 1ng'11 adjacent which maybgpperable accelerating means or draw-,otrol plunger 12 as reciprocated by device 13.'

The furnace 1 is lined with lheat-resistant 35 refractory. material.' Likewise, the way 4, 5,l

10, is lined with material 14. Additionally, the .wa 4 isi; vrovided with roof or cover 15 for holding. ehleat.v The locationl of the opening 3 is so that it serves as a 0 skimmer against surface'impurities flowing into the ,way 4.

Aften'the removal of glass at the o en surface :region 7 there is tendency of t e lass to blister or become seedy 'or bubbles orm therein, due to the chilling action resultant from the gather or from the lift of the glass at the gather' before severing by shear 16. To minimize the effect of this chilling, es-

heating may occur by burners 17, 18.` Additionally, the trough or way 4 may have skimmer 19 between the top surface gather opening 7 and discharge region 11, thereby permitting inin or clarifying of lthe glass so that gob gat ering may occur at region 11 for dual use of this feature.

In the `event the device is to be discontinued as to operation, there may not be necessity for freezing the plunger 12 in the discharge outlet 11, for dam 20 may be lowered in advance of the low o or discharge outlet 11. In the event the discharge outlet 11 is used for gob gathering Vfor feeding an additional ware machine, shears 21 ma be operated in synchronism with the machlne as the blank mold or gather cup 22 is in proper registry therewith. l l

Shouldit be notdesired to have this second glassware Cforming machine supplied, the maintained flow in the way 4 may be effected through the'discharge 11, with the dischar e 11 so controlled that there may be suthcient y rapid ow of the stream of molten glass in the machine 7. This How-od may be cut ,by shears 21 to form sections or gobs 23 to drop between guide rollers 24 upon conveyor belt 25 as operated at a high speed from motor 26 for causing quick travel of such obs 23 and throwing discharge thereof t rou h opening 27 back into the pool 2 of the supp y -tank 1 for re-heating. Other disposition of this glass, as cullet, may be adoptedI as preferre It is accordingly seen that molten glass may v .be supplied by this feeder disclosure to a sucl streamof glass from the discharge 11, re-

' pecially if `.there is to be use of this molten Y receiving means for the molten glass from 10o the latter port, and reheating means between said ports..

2. Molten glass supply means, a way therefrom, said way having an upper port for upper surfae removal of molten glass lfrom the way, said Way additionally having continuous therewith a lower port spaced from the upper port for molten. glass removal, said way providing a path for the How of molten glass from the supply means past the upper port to the lower port, and a conveyor from the lower port to the supply means.

` 3. Molten glass supply means, a way therefrom, said way having intermedlate its length an upper port exposing the upper surface of the molten glass in the way for upper surface upward withdrawal of molten glass from the way, said way therebeyond having qontinuous therewith a gravity flow-0H? lower port for molten glass removal, said way providing a path for the flow of molten glass from the supply means past the upper port to the lower port, and a conveyor from the lower port for returning excess flow from the way to the 5 supply means.

In witness whereof I aix my si nature.
